Vintage SEIKO Tutorial - Seiko 6105 ‘Captain Willard’ Crown Rebuild Process.

We take you step by step through the crown rebuilding process of a Seiko 6139-8119/8110 ‘Captain Willard’. This process renders the watch waterproof again when this gasket is changed in conjunction with the other gaskets.

Fantastic 👍

At first I thought you were crazy with all those gaskets stacked on top of each other but when I saw the finished product I changed my mind completely. I just never thought it would be so much work just to change the gasket on a crown, but you can tell that I'm still learning a lot. Very cool work there.

Thought you'd show us the end result!

Can you share where we can buy this push piece

[@clark3830]

I suggested using two gaskets on stem for a Panerai Luminor and was ridiculed for it. It works.

[@richbonn259]

Are you taking in vintage Seiko's for service?

[@hiranosoranouta9223]

What is the size of the new gasket?

[@mmorey79]

Care to share the size/source of the "sacrificial" gaskets used to pop the washer?

[@BiffTannenBTTF]

I'm curious as to why you don't just cone out the washer to remove it and then put it back in upside down? Would that not work?

[@johntompkins79]

So did your screw the stem back in to the crown?

[@theseikologist]

Yes

[@johntompkins79]

@@theseikologist so you didn’t put anything on it before screwing itnim?

[@theseikologist]

@@johntompkins79 I use loctite on the stem

[@johntompkins79]

@@theseikologist is that required or will it go in without it?

[@theseikologist]

@@johntompkins79 it will thread on no problem without. The loctite just secures it in place to make sure that it can’t come unscrewed accidentally.

What size anvil are you using to apply pressure to the gaskets? Thanks
